Nexus 5 Battery Issues

So I just got a Nexus 5 and today while traveling I noticed massive battery drain. I stopped for dinner at 5:30 pm and was at 27%, I closed all my apps and set my phone on the cubby on my dash while I drove. With no use, no apps, nothing when I got home at 9:30 pm and picked it up and hit the power button I had 5% battery left. This seems excessive to me. I've noticed other times 20% drops in battery with very little use.

Anyone else having issues or advice?
